WebSep 29, 2024 · Using edge as supervision, the heavy imbalance between edge and other pixels hinders the model from learning highly discriminative features for high-quality edge prediction. A weighted loss can be used to alleviate this issue. But we provide a new solution from a totally different perspective.

The gradient of MSE loss is 2 ( y − p), so the largest value of the gradient is 2. The values of cross-entropy loss is bounded below by 0, but increases without bound. The gradient of cross-entropy loss is p − y p − p 2, which is very steep for p far from y. lamina kerdi ducha
